$PECIFIOATION forming part of Letters Patent No; 284,308, dated September 4, 1883.

Application filed April 17, 1883. (No model.)

To all whom it may concern Be it known that I, JOSEPH KLEIN, asub o o ject of the Emperor of Austria, residing in the city, county, and State of New Yoi'lghave inventeda new anduseful Scaffold and Fire-.

Escape, of which the following is a specificaon. My invention relates to improvements in scaffolds and fire-escapes, and its object is to provide an apparatus which can first be used 4 in the, erection of new buildings, and which mayafterward serve as a scaffold tobe used in making repairs, painting, and the like, and which can be kept constantly ready for use as I attain theseobjects by the in the accompanying drawings, in which Figure 1 is a detailed view, in perspective,

j of the entire machine when adjusted for use. i I Fig. 2 1s a similar view of the entire machine folded' up for transportation or storage. Fig. 3 is a detailed view, in perspective, of the pieces which form the hand-rail or sides. Fig. 4 is a similar view of the pieces which, being un folded, form the bottom frame and ends of the machine. Fig. 5 is a side view of one'of the geared shafts by which the machine is suspend-edand operated when in use. Fig. 6 is the same view half reversed to show more j L 0 clearly the connection of the gearing. .Fig. 7 i

is a view in perspective of the crosspieces which form the bottom or floor of the machine.

4 is a vertical section of the entire machine, showing the method of its attachment 5 to buildings.

:Similar letters referto similar p arts throughout the several views.

Theside rails, A A, with mortises to receive the upright posts B B, connected by 0 6, hinged at K, form the frame-work of the machine. a

i c are rods which keep the side rails, A A, in

i position.

D D are the longitudinal pieces which form 1 j l 5 the bottom, and E E are the cross-pieces which hold D D together, and are provided with projections or bolts a a, whichfit into the sockets b b in the frame-pieces G 0, so as to form a solid floor.

. desire to secure by Letters F F are .trucks attached to the frame-pieces G G are the geared shafts attached to the uprights B 'B, by means of which the whole machine is raised or lowered when in use. 7

H and I are'geared wheels placed at right angles to each other and attached to the end of the shaft G, and imparting motion to it when power is applied to the handle J. t is a ratchet whichfalls upon the gear'H.

R is the rope-or chain by which the machine is suspended from a building.

In constructing my invention, I use wood,

iron, or any material suitable for building frame-work, and I carry said invention into effect as follows: The machine being folded, as in Fig. 2, I first unfold the bottom pieces, 0 C, which, when opened, form a stiff unyielding frame-work. The end pieces, B B, are then raised, and the side rails, A, are slipped into the inortises in B B, ready to receive them, and are held in position by the cross-rods c c. The longitudinal pieces D D, connected with the cross-pieces E E, are placed upon theframes O O and held in position by the bolts a a, dropped into the sockets b b, the wholeforming the floor to the machine. The scaffold is then ready for use, and the occupants, having attached one end of the ropes or chains R R to the edge of the roof, the window-sills, or any desired point in the upper part of the building, may raise themselves by turning the handle J, which moves the gear H, which, working into the gear I, attached to the shaft G, revolves it, and by winding up the rope or chain B raises the escape, the machine would be already attached to the building, and could be lowered by the same mechanism as above described.

The use of my device is not, however, confined to any: particular builing, and as it is constructed so as to fold together it is there fore portable, and in case of fire may be used as a life-saving device, raised and lowered by mechanism entirely disconnected with the burning building.

Having fully described my invention and the manner of its operation,what I claim, and

Patent, is-

1. In a seafiold and fire-escape, the bottom 3. In a scaffold and fire-escape, the frame 0 pieces, 0 (l, hinged at K, in combination with 0,13 B, and A A, in combination with the shafts the uprights B B, hinged at L, and the side G G, operated by the gears H and I, substanrails, A A, held in position by the rods a, subtially as described, and for the purpose speci- I 5 5 stantially as described. fied.

' 2. In a seaflold and fire-escape, the frame 0 O, B B, and A A, in combination with the JOSEPH KLEIN; slats D D, joined to the cross-pieces E E, and connected with the frame 0 G by bolts a a and Witnesses: 1o sockets or staples b b, substantially as de- JOSEPH FURNIVAL, scribed, and for the purpose specified.
